Blog: Rental car mobile application development

The world has over a billion cars and not of them are being used. Some people have older vehicles, some don’t have time for using them but both the categories have a common thought — why not lease it and make a quick buck out of idle cars? Luckily, there are always people willing to rent cars for trips and DB Best connects these people together.

The long-reaching app nature allows for attracting customers from all around the world to eliminate storage and reduce middleman costs. Whether it’s someone renting or leasing a car, both parties will require minimum time and effort making deals via several clicks. Car rental application development can be an easy affair and DB Best makes it possible.

Customer viewpoint

Generally, car rental involves two sides: a leaser and a renter. However, we can add extra roles such as insurance service, tax agent, or even ambulance. Let’s see how we implement the main two roles for customer needs.


Car owners can start from filling their profiles with the required info and put the rental price. This, however, isn’t mandatory as the price can be generated automatically based on the car model and the common prices.

Gathering car info is also automatic — for that measure, we use VIN10. The user can simply enter a 17-digit code and the app will instantly upload vehicle specs. Much like a fingerprint, it shows all car features and the manufacturer details to ensure that it’s a real customer.

Once it’s done, all you need to do is wait for the interested person to show up and deliver the car where it will be picked up by a renter. The station will contain a simple kiosk and a QR code reader — it will be the confirmation tool showing that the car is ready and waiting. The system will send this QR code to a renter. After it’s used, the money will be sent to the car owner.


On the receiving end, the renter needs to register in the app and… that’s it! There will be a map showing parking lots with available cars and once a customer taps the preferred vehicle, the system will send a message to the owner. It will show where and when the car and the keys should be left to be picked by a renter after the QR code is entered.

Technologies used

See how we build our car rental apps for both iOS and Android.


Every driver needs a license, that’s why we needed a solid tool for verifying renters’ data. The best way was to implement third party services that scan physical documents and check if customers’ licenses are valid. Checkr API was the perfect choice for background checks, meanwhile demanding car specs was a good security step itself.


This technology makes it a whole lot simpler — after a 17-digit code is entered, the user’s car specs will be automatically uploaded to the system. If there is no code, the car owner can enter car information manually.


To resolve possible customer disputes, we have implemented Record360 API for tracking car conditions and uploading them to the system. From a moment a renter picks a car, the technology allows for making time-stamped and geo-tagged evidence and proving that the equipment was intact.

QR Codes

Stripe API was a perfect choice for enabling QR code payments inside the app. QR was also the solution for check-in and check-out procedures – it became a universal method of operating the app security.


What are the app benefits?

It’s reliable, simple, and is free of the human factor. Just like everyone, the customers value their time and appreciate when it only takes several clicks to get things going.

Once the app omits the staff cost, you become free from paying parking royalties — only the QR code receiver and a small kiosk is what you require.

Why our product?

Middleman risks are minimal risks — as the app owner, your only duty is making people aware that your app exists. Even among other digital platforms, mobile apps have overshadowed their competitors and future generations are leaning towards mobile products more and more.

We, at DB Best, prefer a meticulous approach when making apps and know how to bring complex features to life. Whether it’s local maps, vehicle objects, payment and security systems, or personal data, it will be gracefully incorporated into the app.

Contact us and benefit from the mobile app solutions and see how fabulous it is to cut your costs and make it run smoothly.
